π« sbigtopgm β the glow-up your telescope pics deserve π«
okay bestie, listen. this is the manual page for sbigtopgm, which lives in Sbigtopgm User Manual territory, section 1 of the General Commands Manual. it's a whole little icon and it's about to turn your star pics into something the group chat can actually open. π«Ά
β¨ NAME β¨
sbigtopgm β convert an SBIG CCDOPS file to PGM
no cap, that's the whole job description. short. iconic. π
π SYNOPSIS π
sbigtopgm
[sbigfile]
π¦ DESCRIPTION π¦
This program is part of Netpbm(1). (yeah, it runs with a whole squad, it's not doing this alone π)
sbigtopgm reads an image file in the native format used by the Santa Barbara Instrument Group (SBIG) astronomical CCD cameras, and produces a PGM image as output. Additional information on SBIG cameras and documentation of the file format is available at the Web site, http://www.sbig.com/ . (go look, it's giving very much "reference material", very much "cite your sources" energy π)
sbigtopgm recognizes some variation on the documented SBIG Type 3 format. it's lowkey flexible like that. It allows any capitalization in the header. Like, TYPE, Type, tYpE? doesn't care. β¨ It ignores all whitespace in the header except newlines. So a header line can end in newline, CRLF, or the bizarre LF-CR actually required by the spec. (the LF-CR is fr fr unhinged, the spec really woke up and chose chaos π but we support it, we're not judging.)
π OPTIONS π
There are no command line options defined specifically for sbigtopgm, but it recognizes the options common to all programs based on libnetpbm (See Common Options .)
yes bestie, that means it shows up to the shared-options party wearing the same outfit as every other libnetpbm program. no custom flags. zero. none. that's the whole vibe. π

(the round trip is real. one converts in, one converts out. it's giving bestie duo π)
